L If vibration or chipping on cutting edge occurs, please decrease the cutting condition as width of cut, depth of cutand feed per tooth depending on the situation.Note 2) Recommended cutting speeds apply to tool outside diameter. Please calculate the spindle speed of tool in the following expressions. Spindle speed of cutting tool n(min-1 )=12×Cutting speed vc ÷ Diameter of cutting tool DC ÷ 3.14 L272 INDEXABLE MILLING
